Pronghorn Heaven

I guess it says something about how much we like field biology that, after a grueling season in Lander, Gail Anna and I are willing to go spend another week being field assistants on someone else’s project. On the way back west to California, we stopped at John Byers’ research site to help out with his long-term study of Pronghorn.

John is set up in a beautiful old house, quite close to the National Bison Range. The site is in a picturesque agricultural valley between the Mission Range and Sapphire Range in western Montana. Great views everywhere, and lots of wildlife. It helps that we arrived at probably the greenest time of the year, with spring in full surge all around us. The house is on a ranch with a few horses, cows, and a lot of cute fluffy sheep.

The field site itself is incredible- 30 square miles of rolling meadows and tall hills carpeted with purple lupines and big clusters of yellow mule’s ears. There are a few hundred bison, along with a lot of white-tailed deer and of course the monitored population of pronghorn. John and his recently-finished graduate student Erin know all the individuals, and much of our first week has been tracking everybody down and waiting for the females (does) to give birth. The first birthing date was unexpectedly late this year, but we did get to catch at least one before leaving.

Our travels have also taken us to Yellowstone and Glacier National Parks- two of the truly spectacular places on this planet. Even if I don’t have an update specifically about those, I’ll definitely have some photos up on my flickr site.

Looking Back on the 2012 Season

We haven’t left Wyoming yet, and I don’t consider our season officially done until we’ve washed the vehicles and returned them to Fleet Services at UC Davis, but the crew leaving and having to pack up camp definitely puts me in a retrospective mood. Some thoughts on the 2012 season:

Overall we got REALLY lucky with the weather. This has been an amazingly warm, dry year, and we were rarely prevented from accessing the leks or collecting data. It seemed like we might have gotten a little more wind in the mornings, and the rain-out on our final experiment (when Stacie was going to get to join us on the lek) was a bummer, but otherwise we really could not ask for better weather.

As I said in my last post, the crew was fantastic. This project requires field technicians who completely buy in to what we’re doing, and they seemed to do that. It makes it much more fun when they are nice interesting people who are easy to live with, which they were. Once again, we did a good job selecting these folks out of the pool of more than 70 applicants.

Anna getting video of female behaviors on Cottontail

We collected a LOT of data this year. The arrays were installed relatively early, so we got sound recordings from before or around the peak in breeding. We managed at least two experimental treatments on each lek. Anna collected focal data on courtships and female behavior almost every day.

Gail did a great job turning an idea for a robot into a working tool for interacting with free-living animals. Besides just getting a realistic looking skin on the taxidermy mold, she had to solve challenges like figuring out the best wheels or treads, figuring out how to make the tail bend down when the robot leans forward so the robot isn’t mooning the whole lek. In general, the males really responded well this year.

Having to drop Preacher Lek from our stable of focal leks could have been a problem, but I think we handled it pretty well. Preacher’s replacement, Cottontail, was definitely a challenge, but I feel good about our effort there. Liz (and sometimes Mel) had to put some long hours there waiting for the last birds to leave. There were a lot of birds, and probably some movement of males back and forth from the upper center to our focal area closer to the reservoir. This meant new birds showing up all the time!

Our crew scheduling worked pretty well- it was a little uneven in that Cottontail always had more of everything than either Monument or Chugwater, but there are only so many ways to spread 4 people over 3 leks. Hats off to Mel for being a great floater, and learning the birds at all 3 leks. Although it might not have felt like it sometimes when we had to make last minute changes, but we did a much better job of planning ahead as well. Our crew not only had more frequent mornings off (once every eight days), but often actually knew when those were going to be.

The crew may have spent as much time watching video grouse than they did watching live ones. Collecting video data back in the lab will now be a lot easier, as we will know which males were where for the fembot experiment tapes, focal female courtship tapes, and the sound recording. This was definitely not the favorite part of the job for the crew, but they managed to get it all done.

The "unexplored" valley of Coal Mine Draw, complete with a lek

I found a new lek! And not too far from our camp. I think that’s pretty neat. I got to do counts on several leks I’d never been to. It’s nice to hear from the local managers like Sue and Stan how important these counts are.

 

No high-speed video this year. We still haven’t analyzed the set of clips that Gail collected last year. HSV is always really fun, and can be something the crew starts analyzing here, but we had neither the time nor the specific question that required it this year.

We didn’t spend much time capturing birds this year. This is probably our biggest challenge now- figuring out how to schedule a crew so we can work at night, in the morning, and in the afternoon. Something to think on for next year.

I got to meet Joe Hutto.

It was really fun to see our research area in such a warm year. The season was advanced substantially, so we got to see a lot of plants and animals that we normally miss. And in any year, this is a really special place to get to live and work. The more than 5000 photos I’ve taken this spring can attest to that!

"Super-moon" from a couple of days ago

Full Moon Fever

We get to study the sage-grouse in a really beautiful place here in Wyoming, and at no time is that more evident than during the full moon. There’s just something about seeing a moonrise over a vast expanse of sage, or watching the moon set over the snow-topped Wind River Range that just gives me chills. It’s always disappointing when we get cloudy weather on those days, but for this cycle in early March 2012, we were lucky enough to get stunningly beautiful moonrise and moonset. The moonset in particular was really magical- I was in a blind in the snow on Monument Lek. The birds on Monument had not really come in on any morning we were watching yet, but this morning Becca and I heard bird after bird fly in just as the moon started falling below the horizon. I’ve added a few more photos to the flickr albums- check out the Photos page for the links.

CBC on KQED

Black Oystercatcher, Albany, CA

I mentioned a couple of entries ago that KQED Quest came along on the Oakland Christmas Bird Count and produced a feature for their weekly radio program. Well, that feature aired today. You can read the transcript, and also listen to the program using a link at the top of the page. Also note the Oystercatcher and Turkey photos are mine! I thought they did a really nice job. It’s always a surprise what they might include- Andrea was along and recording all morning, so must have had several hours of recordings to support the story.

New Website Section: Photos

[Note- I have not yet started organizing photos for a WordPress site]

I’ve added an additional page to my website here: Photos! I’ve decided to add this for a couple of reasons. First, I’ve been navigating the world of digital photography for a little while, and about a year and a half ago made the jump to DSLR photography. There are a lot of options when you are just starting out, and it can be confusing to know what accessories to get, upgrading etc. I’ll start to collect some advice there.

Secondly, like many people who enjoy taking pictures but don’t necessarily do it for a living, I’m happy if they can be useful to someone else. If anyone would like to use the images in that section for educational purposes, feel free, all I ask is attribution in whatever presentation you are constructing, and I’d love to know about it! If you’d like to use them in other contexts, please contact me.

I’m still working out exactly how I want to display the photos there, so it may take me a while to populate the page.
